CROSS REFERENCE TO RELATED APPLICATION

This application takes the benefit of and claims priority to U.S.Provisional Application Ser. No. 62/362,272 filed on Jul. 14, 2016, thecontents of which are herein incorporated by reference.

FIELD OF THE INVENTION

The present invention generally relates to tools, and more particularly,to a one piece forged floor scraper designed to retain both 2mm and 4mmscraper blades.

BACKGROUND OF THE INVENTION

Floor scrapers, also known as floor strippers are used to remove tile,glue, wood, etc. from the floors. Through the years floor scrapers havetaken on many changes in shape, size, function, and design. Many presentfloor scrapers consist of a straight steel tube handle with some havinga rubber or special designed hand grip around it. At the working end,the tube is connected to a steel holder, known as a scraper head. Thescraper head holds the scraper blade. Typical conventional floor scraperdesigns use standard scraper blades that are usually replaceable. Bladestypically range in size but the standard 8″ scraper blade is commonlyutilized. The scraper blade is attached to the scraper head by screwsand a flat plate that mates with the scraper head.

In certain aspects, floor scrapers are designed with a broad bladecutting tool having a shank adapted for insertion into the bushingportion of a power-driven hammer mechanism, such as an air-operatedhammer, for cutting asphalt pavement.

Further, many of these floor scrapers and cutter mechanisms comprise ofmultiple parts that require the user to assemble the parts before use.

SUMMARY OF THE INVENTION

The instant apparatus, as illustrated herein, is clearly notanticipated, rendered obvious, or even present in any of the prior artmechanisms, either alone or in any combination thereof. Thus, theseveral embodiments of the instant system are illustrated herein.

In one aspect, the present apparatus introduces a novel floor scrapermechanism comprising a one piece forging design.

Another aspect of the present apparatus introduces a new floor scrapermechanism comprising a one piece forging design, with a working endwherein the working end may retain both 2 mm and 4 mm scraper blades. Inyet another aspect, the system provides a new floor scraper that is userfriendly and easy to utilize.

Yet another aspect of the present apparatus introduces a new floorscraper that provides easy removal of floor coverings such as tile,carpet, adhesives and more.

Another aspect of the present apparatus introduces a floor scraper withan innovative head design which helps to prevent shearing off of thebolt heads as an edge portion disposed for a blade to rest against isintroduced. Further, the floor scraper's all steel design produces along life for the tool and a protective coating prevents corrosion andrust.

In addition, an aspect of the present apparatus introduces a floorscraper that has increased efficiency and higher durability.

In one aspect of the present invention, the floor scraper mechanismcomprises of a hex shank floor scraper system, wherein the hex shank maybe used to attach the floor scraper to a series of mechanicalinstruments or prime motivator systems to create vibration onto theflooring or other surface.

Realizing one aspect of the apparatus is a new floor tool that providesan efficient and durable floor scraper that comprises a one pieceforging design and wherein the working end of the floor scrapermechanism may retain both 2mm and 4mm scraper blades. The new floorscraper is user friendly and easy to utilize, as well as, the innovativehead design helps to prevent shearing off of the bolt heads and the allsteel design produces a long life for the tool. In addition, aprotective coating prevents corrosion and rust.

Referring now to the figures to better illustrate the present apparatus,FIG. 1 exemplifies a perspective view of one embodiment of the floorscraper mechanism 10 fully assembled and functional. The floor scrapermechanism comprises an upper shank portion 12, a handle portion 14, anda working end portion 30 comprising a steel holder 18 or scraper head,and a scraper blade device 20. The steel holder 18 comprises a set ofattachment mechanisms 16, such as flange bolts and flange nuts, andretains the scraper blade device 20. Herein, the upper shank portion 12may comprise of a one and one-eighth hexagon-shaped shank.

FIG. 2 illustrates a bottom view of the floor scraper mechanism 10,wherein the scraper blade device is removed so that the working endportion 30 and the scraper holder 18 is fully visible. Again, the uppershank portion 12 has an upper portion 34 preferably of hexagonal shapeand adapted to fit into the bushing portion of a known type of poweroperated hammer. The hex shank portion 34 terminates in a collar 32which functions to lock the tool into the bushing portion of the poweroperated hammer.

Additionally, located below the collar 34 is the handle portion 14,which may generally comprises a circular cross section, but may bevaried as required for design considerations. The handle portion 14merges into the working end portion 30 and the working end portion 30 isdisposed to retain the steel holder 18. The scraper holder 18 is nextdisposed to retain the scraper blade device 20. The scraper blade device20 terminates at its lower end in a chisel-like edge.

In order to properly retain the scraper blade device 20, the scraperholder 18 may have a series of attachment mechanisms 16 which are inmechanical communication with the steel holder 18 through drilledapertures 38 as seen in FIG. 3.

FIG. 3 illustrates a top plan view of the floor scraper mechanism 10.The drilled apertures 38 are shown. When wanting to attach a scraperblade, a user would align the scraper blade with the drilled apertures38. Then, an attachment means like bolts are in communication with thedrilled apertures 38 and the scraper blade device, securing the scraperblade device to the floor scraper mechanism 10.
